CAL NANO CO2 Checker

Current CO2 checkers on the market today are more suitable for mid-size aquariums. When placed in small aquariums, where space and visual field is limited, the viewer can be unpleasantly distracted from the aquascape.

Cal Aqua Labs’ Nano is designed specially for small aquariums. Measuring approximately 3 cm x 3 cm, it is small enough to appear unobtrusive yet large enough to provide a clear and accurate reading.

• Supplied with 15ml Indicator Solution (4dKH). No mixing nor preparation required.
• Perfect for aquariums 1-15 gallons

Approximate size of unit without suction cup: 3 cm x 3 cm (W x H)
